Lady Justice Smith, one of the appeal judges, said that although the reduction in crew numbers would, to some extent, affect the working conditions of employees, the “disastrous” consequences for BA would be much worse if the contract changes were not implemented.

In a statement responding to the judgment, BA said: “We are pleased with today’s Court of Appeal judgment, confirming that the modest changes we made to on-board crew numbers on flights from Heathrow 12 months ago were reasonable, did not breach crew contracts and can remain in place.

“The changes have made a substantial contribution toward easing the company’s financial position, and our crew have accepted these working arrangements without difficulty.”
